OIL-BURNER.

sPEcIFIGATIoN forming para ofnetrs Patent No. 735,292, dated August 4,1903-.

Application led May 17, 1 902. Serial No. 107,785. (No model.)

Be it known that I, ELI POLLAK, a citizen of the United States, residingat Philadelphia, in the county of Philadelphia and State of Penn-Sylvania, have invented a new and useful Wickless Oil-Burner, of whichthe following is a specification.

This invention relates generally to lamps, and more particularly to awickless hydrocarbon-'lamp ,and the object ofthe invention is to providea simple and efficient lamp of this character which can be utilized inconconsists in the novel features of construction upon the burner.

of the burner, the retort-vaporizer, and theV Fig, 3 is a vertical.sectional view taken through the reservoirV and burner, theretort-vaporizer being shown and` combination, all-of which willbe fullydescribed hereinafter and pointed out in the claims.

In the drawings forming part of this specication, Figure l is aperspective `view of a lamp constructed in `accordance with myinvention, the chimney and mantle being shown Fig` 2 is a top `plan Viewair mixer or commingler.

reservoir A, which may be of any suitable or desirable pattern and isprovided with an air-inlet tube A', to which any suitable form ofair-forcing apparat-usmay be connected.A

B indicates a pipe `which extends into the reservoir to a point adjacentto the bottom, the upper end of said pipe being connected to thecoupling B', in which operates a needle-valve B2 for the purpose ofcontrolling `5o the flow of hydrocarbon from the pipe B to the pipe C,which is also connected to the secured by means of a ring or collarI-I'.

Eig. 5 isA In carrying out my invention I employ a coupling B'and whichis connected at its up- `per end to a retort D, `which is essentially inthe form of-a-drum. A dash-pan E is provided beneath this retort, saidypan being preferably supported by means of a bracket connected to thepipe C.

The burner comprises an essentially cylindrical-shaped casing F, whichis supported upon the standard F', extending upwardly from the center ofthe top of the reservoir;

The casing F is open at the side adjacent to the retort and is also openat theto p. A perforated metal plate G is secured Aupon the open end ofthe casing F adjacenttothe retort, said perforated plate being heldinplace by means of the threaded collar G',and at the open top of thecasing a wire screen H is The casing F is formed with a threaded neckF2, into which screws the pipe-section I,.the airmixer K being attachedto the outer end of said pipe-section, said mixer being essentially inthe form of a hemisphere and provided with a series of perforationsK',through which the air can enter. A valve-casingL is connected to theouter end of the air-mixer K, and in which operates the needle-Valve L',by means ot' which the ow of vapor into the mixer and burner isregulated, said vapor being conducted from the retort D t0thevalvecasing L by means of a pipe M. The casing F has a centralthreaded stud N projecting upwardly from the bottom thereof, and securedupon said stud is a solid metallic body O, the purpose of which is tocause a considerable circulation within the casing, thereby producing acomplete commingling of the vapor and air before passing through thewire screen for combustion, and by producing this complete comminglingof vapor andairl am enabled to provide almost perfect combustion, andthereby reduce smoke and smell to a minimum.

In operation the reservoir is filled with oil to any desired extent anda delinite amount of air compressed within the same. The needle-valve B2is then partially opened, permitting a small quantity of hydrocarbonfluid to pass upwardly into the retort, and a small quantity of alcoholor other combustible fluid is ignited in the flash-pan E, there- ICOcasing F, and while the vapor is so passing a definite quantity of airis being drawn in through the mixer and mixes with the vapor. Thecommingling vapor and air becomes thoroughly mixed in the casing F, andinasmuch as the Hash-pan is still burning a portion of the commingledair and vapor will be ignited at the perforatedplate G and will con-Ytinue to burn at that point, thereby continuing to heat the drum-shapedretort, and thereby complete the vaporization of the fluid. The majorportion of the vapor will pass upwardly through the screen and burnabove the said screen, the solid body O serving to cause a sufcientcirculation prior to combustion to provide for a thorough commingling ofthe vapor and air.

pressure.

By the construction herein shown and described I produce a lamp in whichhydrocarbon oils of every description are thoroughly vaporized. prior tobeing mixed with air, and the fluid so vaporized is thoroughlycommingled with the air prior to combustion, thereby reducing smoke andsmell incidental to combustion to a minimum.

In the drawings hereto annexed and forming part of this specification Ihave shown what I consider the best means for carrying out my invention;but I do not Wish to limit myself to the exact details of construction,as it is obvious that they may be changed or altered Without departingfrom the broad principles of my invention. It will also be understoodthat I do not limit myself to the exact construction and arrangement ofdrumretort, but may employ any suitable construction for carrying outthe vaporization of the iiuid fuel.

Having thus fully described my invention,

The retort is provided with suitable valves to prevent back v what Iclaim as new, and desire to vsecure by Letters Patent, is- Y l. In adevice of the kind described, the combination with a burner perforatedon one side, of a retort arranged adjacent said perforated side, a metalbody within the burner and projecting upward from the bottom of same, anair-mixer connected to the opposite side of the burner and a pipeleading around the burner from the retort to the airmixer.

2. The combination with a cylindrical casing perforated on one side, anupwardly-'extending metal body centrally arranged on the bottom of thecasing, of a gauze top, a retort adjacent the perforated side, anair-mixer chamber on the opposite side of the casing,ra pipe exterior ofthe casing connecting the retort and mixing-chamber, and a valve adaptedto regulate the passage of vapor to the mixingchamber.

3. The combination with a reservoir, of a threaded socket on the top ofthe reservoir, an upwardly-open, cylindrical burner-casing havingiianged openings on opposite sides, an integral projection extendingdownward from-the bottom of the casing, and having a downwardly-open,threaded socket therein, a standard threaded into the said sockets andadapted to support the casing, a pipe secured in one of the sideopenings of the casing, a mixing-chamber carried` by said pipe, aperforated plate secured in the openings in the opposite side of thecasing, a gauze disk over the top of the casing, a flanged ring securedaround the top of Athe casing and adapted to retain the gauze inposition, a retort adjacent the perforated plate, means for feeding oilto the retort and burner-casing, and an upwardly-projecting metal bodyarranged within the casing.
